Abstract

Porous sheet silicate in combination with a polyol-containing aerosol forming substance.

Description

The present invention relates to a substitute for hookah tobacco especially for use in shishas.

More recently, favored by increased nonsmoker protection, it has become popular to consume in public places and privately, rather than tobacco products, substitutes that are less harmful to the user and his fellow human beings and are not covered by nonsmoker protection. One of the variants uses flavored mixtures in which one or more mixture components form an aerosol upon heating, which is inhaled by the consumer. Heating may or may not be provided by combustion processes (e.g., high purity coal, and especially coking coal). As the aerosol (actually: the fog) forming substances have established because of their low toxicity polyols such as glycerol and propylene glycol. Other mixture components are a variable proportion of water and, as a main component, typically molasses or other organic materials, occasionally also tobacco. In the latter form, such compositions are known for consumption with hookahs or hookahs. If combustion processes provide the heat source, fine dusts usually form, which are inhaled.

Recently, such mixtures have been used to infiltrate mineral carriers (so-called "steam stones") which release the infiltrate during the heating process without irreversibly altering its structure. Such products are known under the name Shiazo. Since the mineral carriers do not irreversibly change their structure when heated, the carrier minerals can theoretically be used multiple times. However, in practice, this encounters significant problems, which is why very few consumers are willing or even able to do so. For example, it is often impracticable to completely volatilize the flavorings out of the known carrier so that undesirable and sometimes unpleasant flavor blends may occur with multiple uses. Also, the impregnation of known support materials is sometimes very tedious or requires a certain skill of the consumer with heat sources. In addition, the use of carrier material is perceived as proportionately too high.

The aim of the invention is to provide a solution to the problems mentioned, in particular to provide a combination of carrier material and infiltrate, which allows a proportionately lower use of material.

For this purpose, the invention proposes to use porous phyllosilicates instead of skeletal silicates (for example zeolites) and to combine them with a polyol-containing aerosol-forming substance. In this case, the porous sheet silicate can be impregnated in particular with the polyol-containing aerosol-forming substance. Furthermore, the invention proposes the use of phyllosilicates as an aerosol-forming carrier in a mixture with flavored by-products for inhalation use.

In preferred embodiments, among the phyllosilicates are those which have been expanded by a swelling process and / or for other reasons have a particularly high absorption capacity for liquid mixtures, such as the aerosol-forming substance. In particular, three-layer silicates are preferred, and among these in turn, those from the vermiculite group or vermiculite (Strunz's classification 9.EC.50). Vermiculite is known to expand, for example, during rapid heating by a multiple in a layering direction (see, eg EP 2 150 506 B1 ). The inventor has found that such materials are outstandingly suitable for receiving large amounts of liquid aroma mixtures and even completely releasing them again under mild heating, in the form of an aerosol. Since these phyllosilicates are completely unproblematic toxicologically (unlike silicate fibers, for example) they are optimally suited for use in a further aspect as a water pipe tobacco substitute.

In further preferred embodiments, the polyol is wholly or predominantly (i.e.,> 50%; all figures in mass%) glycerin.

In further embodiments, the liquid mixture consists predominantly (> 50% by mass) of molasses. It is preferred if the proportion of water is below that of the polyol; In particular, the water content of 5-40 mass%, 5-25 mass% or 10-20 mass%, that of the polyol 2-35 mass%, 2-25 mass% or 5-15 mass%, the the molasses is 50-95% by weight molasses, 70-85% by mass or 75-85% by mass or even up to 90% by mass. By contrast, the proportion of the aromas is subordinate and is typically up to 5% by mass or <1% by mass. Typically, however, low mass fractions of flavors, on the order of> 0.001% by mass, are present. The ratio of the molasses content of molasses to water may be between 4.5: 1 and 5.5: 1 and in particular 5: 1.

In preparation for consumption, either by a manufacturer or by the consumer himself, the porous sheet silicate is soaked in the liquid mixture. This process is conveniently carried out in the heat (40-80 ° C), otherwise it is very slow from doing. Also the production The liquid mixture of the components is conveniently carried out at a moderate elevated temperature (30-50 ° C).

For consumption, the porous phyllosilicate impregnated with the liquid mixture is heated by supplying heat just to the extent that the polyol forms an aerosol which feeds the consumer with the inhaled air flow. Depending on the source of heat, the air stream may also contain combustion gases; this is not necessary, but on the other hand, it does not necessarily have to be ruled out, although certain gases such as carbon monoxide and particulate matter pose a health concern. The flavorings contained in the liquid mixture are supplied to the consumer together with the aerosol.

Similarly, it is also possible to administer therapeutic agents in place of or in addition to the flavorings by inhalation.

Depending on the absorption capacity of the porous layered silicate, the volume ratio to the liquid mixture can be between 1: 1 to 1:10; Values between 1: 2 to 1: 8, more preferably between 1: 4 and 1: 6, are preferred. The bulk volume of the porous phyllosilicate is used as a basis.

The porous support made of phyllosilicate is used in embodiments as granular granules. Preferred nominal grain sizes are 1-8 mm, more preferably 1.5-5 mm or 2-3 mm. Too much grain affects the delivery process of the aerosol; smaller particle sizes than 1 mm are difficult to handle.

The above embodiments illustrate the present invention by way of example only. Those skilled in the art will recognize that many modifications, additions and substitutions are possible, without departing from the scope of the invention disclosed in the following claims.
